Wago’s / conductor preparation

Baldyhugh
Hi


I find myself using the lever 221 wago’s more and more now mainly for lighting circuits but have a question regarding conductor preparation prior to insertion in the wago once the required amount of insulation is stripped off. A solid conductor seems to just go straight in but do you twist a stranded cable and a flexible cable or put them in untwisted? I can’t find any guidance on the box or on the wago website. What do other users of these great little inventions do with them?


Thanks

    I guess the spring-loaded grip on the conductor is what gave me the impression that they should only be a temporary fix - have I misunderstood then, and are they okay for permanent work?  


    I keep a few of the older style ones with my tester for R1+R2 and ring tests.


    My understanding is that all Wagos are maintenance free (in a suitable enclosure), but for T&E the 773 series are cheaper. Clearly the push in types are not suitable for fine-stranded. A lazy twist seems to be the right thing to do.

    would you twist the stranded aswell? I remember a while back the debate about meter tails in a cage clamp terminal of a consumer unit main switch for example. The consensus was to keep the strands straight for a better termination. I think that the smaller conductors, say 1.5mm suffer less from strands rearranging than the larger but would be interested to hear other opinions
